IMPROVEMENT IN PLUMBERS GRA PPLES.

Specification forming part of Letters Patent No. 179,533, dated July 4, 1876; application filed June 6, 1876.

To all whom it may concern Be it known that I, WILLIAM H. DEWAR, of the city, county, and State of New York, have invented a new and Improved Plumbers Grapple, of which the following is a specification:

Figure 1 is a side elevation. Figs. 2, 3, and 4 are detail views.

Similar letters of reference indicate corre-- length; the outer end is also curved transversely, with the convex side outward. A

short arm, E, is attached to the movable jaw D, to which a rod, 1), is pivoted. The rod b and pipe B are held together at intervals by rings 0, whichv admit of moving the rods in the direction of their length, but prevent their springing apart. The jaw D is provided with teeth d, and the jaw A is provided with "a single spur, e.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of jaw A, attached to rod B, having oflset at U, and provided with spur c, movable jaw D, having teeth d, pivoted at a, and having a short arm, E, and the pivoted rod 1), the rod and pipe being held by rings 0, all as shown and described.
